The utility model aims to mainly solve the difficult technical problem that maintaining the existing air filter of the automobile depends on the regular check carried out by drivers or the abnormal conditions of the automobile. The technical scheme of the utility model is that the air filter alarm device for an automobile comprises a pressure sensor, an analog-to-digital conversion circuit, a single-chip, an LCD (liquid crystal display) and an alarm, wherein the pressure sensor is mounted in the air filter of the automobile; the output terminal of the pressure sensor is connected with the input terminal of the analog-to-digital conversion circuit, and the output terminal of the analog-to-digital conversion circuit is connected with the input terminal of the single-chip; the output terminal of the single-chip is connected with the input terminal of the LCD and the input terminal of the alarm; the LCD is mounted in the control board of the automobile and used for displaying the operating condition of the air filter; and the alarm is also mounted on the control board of the automobile.
Description
Technical field
The utility model relates to a kind of car air filtering core warning device, and it belongs to a kind of automobile warning device.
Background technique
Though air filtering core is one of many component of automobile, to automobile, particularly to great influence is arranged in working life of motor.If there is not the filtration of air filtering core, motor will suck the air that contains dust, particle in a large number, causes cylinder heavy wear; But air filtering core is long-time to be used or uses in the big environment of dust storm and will stick dust in air, and this not only makes its filter capacity descend, but also can hinder the circulation of air, causes the mixed gas overrich and makes engine operation undesired.Therefore, in time the maintaining air filtering core is vital.Maintaining to car air filtering core at present mainly still relies on driver's regular hand inspection or judges inspection according to the abnormal conditions of vehicle, wastes time and energy, and potential safety hazard is difficult to timely investigation, brings hidden danger to traffic safety.
Summary of the invention
The purpose of this utility model is that the maintaining that solves existing car air filtering core also need rely on driver's regular hand inspection or according to the abnormal conditions judgment technology difficult point of vehicle, provide a kind of car air filtering core warning device that can monitor and report to the police the working state of air filtering core in real time.
The utility model is to solve the problems of the technologies described above the technological scheme of taking to be: a kind of car air filtering core warning device, wherein: this device comprises pressure transducer, analog to digital conversion circuit, single-chip microcomputer, LCD display and alarm, pressure transducer is installed in the car air filtering core, the output terminal of pressure transducer is connected with the input end of analog to digital conversion circuit, the output terminal of analog to digital conversion circuit is connected with the input end of single-chip microcomputer, the output terminal of single-chip microcomputer is connected with the input end of the input end of LCD display and alarm, LCD display is contained in the vehicle console to show the working state of air filtering core, and alarm is contained on the vehicle console.
Described pressure transducer is a B/P EGR Back Pressure Transducer EGR.
The beneficial effects of the utility model are: the utility model car air filtering core warning device, under the situation that does not influence automobile normal running, the working state that can show current car air filtering core for a long time accurately, whether the prompting driver should safeguard air filtering core, effectively prevent because the engine air that the obstruction of air filtering core causes does not circulate, cause the mixed gas overrich and situations such as engine operation is undesired are taken place, guarantee the cruising of automobile.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
As shown in Figure 1, a kind of car air filtering core warning device in the present embodiment, wherein: this device comprises negative pressure pressure transducer 1, analog to digital conversion circuit 2, single-chip microcomputer 3, LCD display 4 and alarm 5, negative pressure pressure transducer 1 is installed in the car air filtering core, the output terminal of negative pressure pressure transducer 1 is connected with the input end of analog to digital conversion circuit 2, the output terminal of analog to digital conversion circuit 2 is connected with the input end of single-chip microcomputer 3, the output terminal of single-chip microcomputer 3 is connected with the input end of LCD display 4 and the input end of alarm 5, LCD display 4 is contained in the vehicle console to show the working state of air filtering core, and alarm 5 is contained on the vehicle console.
Working principle of the present utility model is: setting pressure sensor 1 (negative pressure) in air filtering core, and pressure transducer 1 is set in specified value, and when air filtering core new the time or when not having dust, alarm 5 is not reported to the police, and LCD display 4 shows normal.When the certain fare register of automobile running or air filtering core have dust or other foreign matter, when causing the engine air air inlet not smooth, the pressure of B/P EGR Back Pressure Transducer EGR 1 increases, and simultaneously pressure signal is reached analog to digital conversion circuit 2, after pressure signal is changed through analog to digital conversion circuit 2, entering single-chip microcomputer 3 handles, processing result is sent into LCD display 4 and alarm 5 simultaneously, reminds the driver, can clear up or has changed air filtering core, also avoided simultaneously the increase of oil consumption, the configuration that has also improved automobile.
Claims (2)
1. car air filtering core warning device, it is characterized in that: this device comprises pressure transducer, analog to digital conversion circuit, single-chip microcomputer, LCD display and alarm, pressure transducer is installed in the car air filtering core, the output terminal of pressure transducer is connected with the input end of analog to digital conversion circuit, the output terminal of analog to digital conversion circuit is connected with the input end of single-chip microcomputer, the output terminal of single-chip microcomputer is connected with the input end of the input end of LCD display and alarm, LCD display is contained in the vehicle console to show the working state of air filtering core, and alarm is contained on the vehicle console.
2. a kind of car air filtering core warning device according to claim 1 is characterized in that: described pressure transducer is a B/P EGR Back Pressure Transducer EGR.
